Penicillinase-producing Neisseria gonorrhoeae ophthalmia neonatorum in Singapore.

Abstract
The problem of ophthalmia neonatorum due to penicillinase-producing N. gonorrhoeae (PPNG) has grown with the increasing prevalence of PPNG strains in Singapore. The epidemiological trends, clinical features and treatment of ophthalmia neonatorum due to PPNG were determined from the case histories of 11 babies with this condition treated between 1978-1980. All 11 cases were cured with a single i.m. injection of 0.5 g kanamycin and 1% kanamycin eyedrops instilled for 3 days. In 6 of the 11 mothers, a non-PPNG strain was isolated.
